“Philip Glass is a musician of extraordinary ability, and chooses his collaborators well: Cocteau, Wilson, Freyer…he swims like a fish through the waters of the marketplace that contemporary society has become. Building on a foundation of serious music, and with more than a light flirting with light music, Glass has done his bit to attract a new audience to opera. His minimalism has been a crucial reference point for musical aesthetics over the past few decades, and in The White Raven is put at the service of a poetic and ironic text by the Portuguese writer Luisa Costa Gomes. It’s music with more tunes than we’re used to from Glass, and here receives strong support from the production’s visual element…An all-around success for the Teatro Real.”
